Ecu help? Motronic or jetronic

Post by MikeDakin »

Hi guys having a few problems finding out if I have motronic or jetronic. Only have 2 ecus which makes me believe its motronic but have read somewhere that all B5204f engines were jetronic. Thanks in advanced!

Jetronic.
One is for engine...one for ignition.
If it would be an automatic...it would have 3rd (TCM)for transmission.
